if the Beijing Shanghai high-speed railway is the bright pearl of the world's passenger high-speed railway, then Menghua railway is the peak of China's heavy haul railway. As a new strategic channel for the country's "coal transportation from the north to the South", the Menghua railway starts from haole in Inner Mongolia to Baoji in the north and ends at Ji'an in Jiangxi. It spans seven provinces and regions including Mongolia, Shanxi, Shaanxi, Henan, Hubei, Hunan and Jiangxi, with a total length of 1837 kilometers. The planned and designed transportation capacity is 200million tons/year, and the planned annual coal transportation capacity is 200million tons. It is the longest mileage heavy haul railway in the world

previously, China's "north to South coal transportation, they donated 100000 US dollars to the American youth club for men and women" coal transportation line mainly has three lines: first, the Datong Qinhuangdao line (Datong, Shanxi to Qinhuangdao, Hebei) built in the 1980s, with a total length of 653 kilometers, and the coal transportation volume reached 400 million tons in 2010; Second, Shenzhou Huanghua Railway (composed of Shenmu Shuozhou railway and Shuozhou Huanghua railway, from Shenmu in Shaanxi to Shuozhou in Shanxi to Huanghua in Hebei), was opened in 1996 and fully completed in 2002. At present, the annual transportation capacity is about 70 million tons; The third is the Houyue line (from Houma in Shanxi Province to Yueshan in Henan Province, extending to Rizhao in Shandong Province in the East), with an annual transportation capacity of more than 100 million tons

these three existing lines have obvious common characteristics. They all start from Shanxi and Shaanxi, end at North China ports, and coal goes to sea through ports

this coal transportation pattern has brought great imbalance: on the supply side, China's main coal production areas are Shanxi, Shaanxi and Inner Mongolia provinces (autonomous regions). Shanxi and Shaanxi coal are easy to go abroad, while Mongolian coal is difficult to export. At present, it mainly depends on trucks, and the transportation capacity has become the bottleneck restricting its development; On the demand side, the coal transported from the port is mainly transported to coastal cities (East and South China). Central China has been in a state of no coal and lack of coal. For a long time, the gap of power coal in Central China has been a big worry for the people

since the implementation of coal de capacity, the coal mines in Hubei, Hunan and Jiangxi provinces have continuously withdrawn. In 2017, the coal output of the three provinces was less than 30million tons. Compared with the coal consumption demand of 300 million tons, the coal transfer in demand of other provinces was as high as 270 million tons. In this case, it is urgent to build a new coal transportation line connecting north and South and central China of Inner Mongolia

in addition, Menghua railway passes through many railway blank areas, and the coal transportation in these areas is still mainly dependent on cars. But according to tanxiaoping, director of the Comprehensive Transportation Institute of the planning and Research Institute of the Ministry of transport, this is the worst choice. Highway coal transportation is equivalent to consuming high-grade energy and transporting low-grade energy. With small transportation volume, high energy consumption, great potential safety hazards and long transportation time, it is the most uneconomical, environmentally-friendly and unreasonable way of coal transportation

"so building roads here is equivalent to transporting coal for the country." Fang Rongcai, Secretary of the Party Working Committee of bid 3, calculated an account. Based on the annual transportation capacity of 200 million tons designed by Menghua railway, the same transportation volume requires more than 6 million semi trailers with a carrying capacity of 33 tons. It is learned that at present, there are only about 3.5 million trucks with a total mass of more than 12 tons in China

Menghua railway will also dock with Xingquan railway and go to sea through Quanzhou port, reducing the transportation pressure of Jiaozhou Liuzhou Railway and sea transportation from Qinhuangdao to southern port. The connection of multiple coal gathering and distribution lines, as well as the gradual change of hot metal, are changing the industrial intermodal transportation. After completion, in addition to the feeder railway, the waterway carrying capacity of the Yangtze River, Han River, Xiang River, Gan River and even Quanzhou port in the long term will be used to build a three-dimensional transportation system. It has spread from line to surface, benefiting most of China

Kai is a large-scale precision testing instrument formed by giving full play to the respective strengths of motors. It not only distributes the coal resources in the "energy triangle" area of Inner Mongolia, Shaanxi, Gansu and Ningxia, but also ensures the energy supply in Central China such as Hubei, Hunan and Jiangxi, and promotes the economic and social development along the line. It is a major measure to promote the implementation of the strategy of western development and the rise of central China. Carrying out railway intermodal transportation through the Yangtze River can provide energy supply along the Yangtze River, which is conducive to the construction of China's Yangtze River economic belt and an important measure of the "the Belt and Road" construction. In addition to freight transportation, some sections of the line will also adopt mixed passenger and freight transportation, and operate 200km/h EMU trains. Give full play to its maximum function

not only that, Menghua railway is the longest heavy haul railway in China, but also the longest heavy haul railway in the world built at one time. The construction of Menghua railway will accumulate the experience of heavy haul railway construction and narrow the gap with the United States, Australia and other countries with developed heavy haul railway. In the future, a "Eurasian heavy rail" channel can be built through Mongolia to connect Europe and Asia and benefit the world
